A prenuptial agreement is only valid if it is completed prior to marriage. After a couple is married, they may draw up a post-nuptial agreement. In the United States, prenuptial agreements are recognized in all fifty states and the District of Columbia.
Osmosis - the diffusion of water (across a membrane) Water will move in the direction where there is a high concentration of solute (and hence a lower concentration of water. A simple rule to remember is: Salt is a solute, when it is concentrated inside or outside the cell, it will draw the water in its direction.
Osmosis is the movement of water molecules from an area of high water concentration (weak/dilute solution) to an area of low water concentration (strong/concentrated solution) through a partially permeable membrane.s we know each cell is surrounded by a cell membrane. This membrane has tiny holes in it which allow small molecules to pass through but not large ones. Due to this nature the cell membrane is described as being partially (or selectively) permeable. Osmosis is a special kind of diffusion involving water molecules.
